Cable joint also known as Cable Head. After the cable is laid, in order to make it into a continuous line, each segment of the line must be connected as a whole, these connection points are called cable joints. The cable connector in the middle of the cable line is called the intermediate connector, and the cable connector at both ends of the line is called the terminal head. The cable joint is used to lock and fix the incoming and outgoing lines, playing the role of waterproof, dustproof and anti-vibration. The cable joint, also known as the cable head, is an important step that must be taken after the laying of the cable in order to make it a continuous line. These connecting points not only connect each segment line as a whole, but also in the middle and end of the cable line have different names. In the middle, these connectors are figuratively called intermediate connectors, and at both ends of the line, the terminals, are called terminal heads. The main function of the cable joint is to lock and fix the position of the incoming and outgoing wires. The utility model makes use of professional technical means to fasten and fix the cable core properly to ensure the stable operation of the cable line under various environmental conditions. In addition, it can also play an important protective role, to prevent water, dust and other foreign intrusion into the cable, and reduce the impact of external vibration on the cable.
